Activity 3. Big bang, the origin and the expansion of the Universe

The big bang theory


In 1927, an astronomer named Georges Lemaître had a great idea.
He said that many years ago, the universe began as a simple point.
He said that the universe had expanded and expanded to its current size,
and that it could continue to expand.


In the origin of the universe, everything was small and united.
It was nothing like what we see now.
As all of that expanded and took up more space,
the universe began to cool down.


The small particles clustered together. And they formed the atoms. Then those atoms clustered together. After a long time, atoms came to form stars and galaxies. The universe is 13,800,000,000 years old.
